Press this soft key to preset sweep conditions to the default state of full band sweep, 201 data points, Quad display, 4 traces (S11 Smith, S21 Log Mag, S12 Log Mag, S22 Smith), 10 kHz IFBW, S21 Log Mag display, High output power, continuous sweep. This also turns off markers, limits, and calibration.
Save
Press this soft key to open a dialog box to name and save the current operating settings, allowing them to be recalled later in order to return the instrument to the state it was in at the time that the setup was saved.
Caution: Use the Change File Type soft key (in the “Save (Text Entry) Menu”, refer to the file management instructions in the user guide for your instrument) to set the file type to “Setup (with CAL)”, if it is currently set to another file type.
The saved setup is named by entering text. Use the Shift key to select an upper case letter. Use the Left/Right directional arrows to move the cursor position. Press Enter to save the setup.
Recall
Press this soft key to open a selection box that allows selection and recall of a previously stored instrument setup. The Recall menu also opens (refer to the file management instructions in the user guide for your instrument). Use the Recall menu soft keys to work within the selection box.

Resolution Per Div
Press this soft key to set the number of units that are displayed between horizontal reticlereticle lines. Units depend upon frequency, time, and distance settings. Use the Up/Down arrow keys, the keypad, or the rotary knob to set this parameter, then press the Enter key or the rotary knob.
Reference Value
Press this soft key to set the value of the Reference Line. Use the Up/Down arrow keys, the keypad, or the rotary knob to set this parameter, then press the Enter key or the rotary knob.
Reference Line
Press this soft key to set which horizontal graph reticle is at the reference value. The reference line is indicated by a small colored triangle along the right edge of the graph. Use the Up/Down arrow keys, the keypad, or the rotary knob to set this parameter, then press the Enter key or the rotary knob.
Aperture %
Press this soft key to set the aperture from 2 % to 20 % of the display. This soft key appears only when a graph type of Group Delay has been selected in the measurement menu. Group delay is a measurement of “Change in phase / change in frequency.” The aperture setting is used by the VNA Master to determine how large a change in frequency to use in this calculation.
Use the Up/Down arrow keys, the keypad, or the rotary knob to set this parameter. When using the keypad to enter a value, an Enter soft key appears in the active function block. The value can be set by pressing this soft key, the Enter key, or the rotary knob. Press the Esc key to exit without changing the aperture.
Active Trace
Press this soft key to open the Active Trace Selector List Box and choose a trace.
Autoscale
Press the Autoscale soft key to automatically adjust the Resolution Per Div and Reference Value so that the trace for the current measurement is shown in the middle of the display.
Press the Scale hard key to access the Scale Menu. The Scale menu is used to set the measurement display for optimum viewing. The type of scale menu displayed depends upon the graph type that has been selected in the meas menu. For example, if Graph Type is selected to Smith Chart, then the pressing the Scale hard key opens the Smith Scale Menu. If the Graph Type is selected to a polar graph type (such as Linear Polar), then the pressing the Scale hard key opens the Polar Scale Menu.
